Neuronal maturation and axon regeneration: unfixing circuitry to enable repair
Mammalian neurons lose the ability to regenerate their central nervous system axons as they mature during embryonic or early postnatal development. Neuronal maturation requires a transformation from a situation in which neuronal components grow and assemble to one in which these components are fixed and involved in the machinery for effective information transmission and computation. To regenerate after injury, neurons need to overcome this fixed state to reactivate their growth programme. A variety of intracellular processes involved in initiating or sustaining neuronal maturation, including the regulation of gene expression, cytoskeletal restructuring and shifts in intracellular trafficking, have been shown to prevent axon regeneration. Understanding these processes will contribute to the identification of targets to promote repair after injury or disease.
期刊介绍:
Nature Reviews Neuroscience is a journal that is part of the Nature Reviews portfolio. It focuses on the multidisciplinary science of neuroscience, which aims to provide a complete understanding of the structure and function of the central nervous system. Advances in molecular, developmental, and cognitive neuroscience have made it possible to tackle longstanding neurobiological questions. However, the wealth of knowledge generated by these advancements has created a need for new tools to organize and communicate this information efficiently. Nature Reviews Neuroscience aims to fulfill this need by offering an authoritative, accessible, topical, and engaging resource for scientists interested in all aspects of neuroscience. The journal covers subjects such as cellular and molecular neuroscience, development of the nervous system, sensory and motor systems, behavior, regulatory systems, higher cognition and language, computational neuroscience, and disorders of the brain. Editorial decisions for the journal are made by a team of full-time professional editors who are PhD-level scientists.
